Serial No. 300,211.

' machine of this character which will be of a simple and compact construction, and effective, efficient and automatic in operation. To the attainment of theseends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimedl and shown in the accompanying drawings illustrating this invention and in which A Figure 1 is a vertical, longitudinal sectional view taken on line 1-1, Figure 2, of a machine of this character constructed in accordance with the principles of this invention.

Figure 2 is a horizontal sectional 'view taken on l1ne-2-2, Figure 1.

Figure 3 1s a detail horlzontal sectional i view taken on line 3-3, Figure 1.

ReferringV more particularly to the drawingsthe numeral designates a suitable supiporting platform yor table upon which the cartonsare delivered. Reciprocably mounted above the platfor 10 is a plunger or ejector 11 vvhich may be of any desired construction and-is provided with a rearwardly deected .or flanged portion. 12, and the plunger is adapted to be given areciprocable movement-in any desired or suite able manner. A" simple and eilicient means for accomplishingthis result embodies a shaft 13 .which is the main drive shaft of the mechanism, and this shaft receives its mo; tion from any suitable source of power, pref-` erablv through the medium of a sprocket wheel 1.4 'secured to the shaft and a drive belt plunger 11 and or chain 15 which passes.v over the sprocket and is itself given motion from any suitable y source of power (not shown) 'This shaft 13 is preferablyv continuously rotated-and securedv thereto for rotation threwith is a toothed element 16 with which a dog-17 cooperates. The dog 17 is pivotally mounted intermediate its ends as at. 18 upon a disc 19, which latter is loosely mounted upon the shaft 13. A spring 20 is carried by the disc 19, one end of the spring resting against a fixed member 21 on the disc and the other end of the spring contacts with the end 22 of the dog 1 7 and tends normally/to move the dog in a direction that it will engage the toothed element 16 and thereby lock the disc 19 for rotation with the shaft 13. A rod or member 23 is pivotally connected at one end as at 24 withthe disc 19 and is connected at vits other end as at 25 with a link 26, which latter 1s in turn connected as vat 27 with an e arm 28 pivotally mounted upon a support 29. A link 30 is pivotally connected at one end .as at 3l with an arm -or stem 32 that is connectedl with the ejector 11 and the link 30 iS pivotally connected atl itsother end preferably by mealieL-fof the same pivot 27, with the arm 28 so that when the disc 19 is locked to the i shaft 13 a rotationof the disc will cause a reciprocatory movement to be imparted to the a rocking movement to the arm 28. V

' The articles 33 which are to be packed may be suppliedin any suitable manner, preferably by\means of an endless conveyor 34 having flights 35 thereupon suitably spaced and the conveyor passes over an idler 36 and also a pulley 37, the latter having connected with it for rotationtherewith a sprocket wheel 38 over which a sprocket chain 39 passes and the sprocket chain 39 also passes over a sprocket Wheel 40 which is connected' with the shaft 13.

The' articles 33 when placed upon the conveyor 34 will be delivered therefrom into a chute 41 and from the chute the articles will drop upon the-supportingV platform 10 until a predetermined number of articles have been superposed upon the platform or support 10,

afterwhichthe ejector 11 willbe operatedand.

the predetermined number of superposed articles will then be moved or shifted upon the supporting platform so as to be moved out of the way of further articles being delivered f upon the supporting platform and will tobe . hereinafter described, and by such latter ejector delivered into the casing.

As the articles are fed by the conveyor 34 they will pass fromthe conveyor into the chute 41 by 'reason of the fact that the flights will be moved out of the way and Willpass through a suitable slot 42 in one wall of the chute 41. Y

In order to maintain the forward end of the articles -against dropping into the chute 41 before the article is completely delivered from the conveyor 34, any suitable means may be provided. To that end there may be provided a s ring controlled member 43 which is arrange inthe path of movement of the foremost advancing article to be engaged by the article and to co-operate with the adjacent Hight 35 to frictionallyhold the article until it 1s delivered in a proper position with respect to the chute 41 that it will drop therethrough. This is accomplished by means of a sprin 44 whichis anchored at one end as at 45 to a xed support and is connected as at 46 with one end of an arm 47, which in turn is connected with a rock shaft 48. Secured also to the rock shaft 48 is an arm 49 which is ctnnected as at 50 with the member 43. The

arm 47 may be provided with a series of openings 51 whereby one end of the spring may be adjustably secured to the arm for varying the stress of the spring. f

Arranged beneath the member 43-is a pivotally mounted member 52 with which another .Iig'otally mounted member^53 cci-operates.

e member 53 is preferably provided with a counter-balance wei ht 54, and connected with lthe member 52 1s an a'rm 55. These members 52 and 53 project into the chute 41 within the path of movement of the article 33 which has been delivered thereinto and serve as a means for temporarily supporting the arf `ticle and are both adapted to'be rocked by the article as the article passes from the chute 41 to be delivered upon the platform or support 10.

The operation' of the member 52 by the advancmg article also controls the operation of the plunger or ejectorll and this is accomplished preferab y through the medium of a rod 56 which is pivotally connected as at 57 with, the arm of the member 52. The other end of the rod is pivotally connected as at 58 with a pivotally mounted member 59 that rocks about a shaft 60.

Secured to the shaft 60 is a ratchet wheel 61 with which a spring controlled pawl 62 that is carried by the member 59 cooperates. Connected` also with the shaft 60 for rotation therewith isa cam 63 which is .adapted to engage an anti-friction roller 64 carried by an extension 65 on anv arm or lever, 66, the latter bein pivotally mounted as a-t 67. One end 68 of t e arm o r lever 66 is adapted to be moved into the path of movement of theend 22 of the dog 17 which is carried by the disc 19. A spring 69 is connected by one end to the arm or lever 66 and is anchored as at 70 to alixed support. The spring 69 tends normally to move the end 68 of the arm or lever 66 into the path of movement of the end 22 of the dog. 17, and a stop 71 may be provided for limitmg the movement of this arm 66. Thus when the end 68 of the arm 66 is moved into the position shown in Figure 1, and when the dog 17 is in engagement with the toothed element 16, and also when the disc 19 is rotating in the direction indicated by the arrow in Figure 1, it will be manifest that when the end 22 ofthe dog 17 enga s the end 68 of the armv66 the dog 17 wlll rocked against the stress of the spring 20 to move it out of engagement with the toothed member 16 and thereby arrest the movement of the plunger or ejector 11.

' ofthe p un The time iii the c cle of operation of the machine at which t e cam 63 will rock thearm or lever 66 is controlled by the number of teeth upon the ratchet 61 and the number of teeth on the ratchet corresponds to the number of packages or articles which `it is desired to superpose u on the platform or support 10 be ore the p unger 11 is operated. Thus as the articles 33 ass the member. 52 t0 rock it each articles wlll impart one step of rotation to the ratchet wheel 61 until the last article of the predetermined number engages and passes the member 52. At this time the cam 63 will rock the arm 66.

When the predetermined lnumber of articles have been superposed upon the platform or support 10 in advance of the plunger 11, the plunger will be operated and will move the articles upon the' supporting causing the deflected portion 12 o er to pass beneath the incoming articles and prevent them from being discharged from the chute' 41'upon the su pprting platform 10. After a redetermine number of operations ger 11 to move a predetermined number of tiers or layers of the articles upon the supporting platform 10, the latter will be positioned 1n front of another ejector or plunger 72 to be moved by the latter upon the supporting platformf 10 and in a direction transverse to the direction of the movement of the articles by the plunger 11. l,The

los

platform, the plungllt plunger 72 in its ,operations will move the' in any deslred or suitabley manner, but preferis operated. To that end there is provided a rock shaft 77 that has connected fwith it a rod 78 which is adapted to be positioned in' the ath of movement of one end of a d o 79, slmilar to the dog 17 that co-opelrates Wit the toothed memberSO- carried by a disc 81', similar to the disc 19. This disc 81 is connected by means of a rod 82 throughthe medium of links 83-84 -and arm 85 with a stem or projection 86 that is connected with'the plunger or ejector 72, similar to the connection of the disc 19 with the plunger'll. The rod 78 is adapted to be operated s0 as to release the dog 79 preferably by means of a cam 87 secured to a shaft 88. which shaft in turn is 'connected by means of gears 89-90 with a gear 91, the latter meshing with a gear 92 carried by a shaft 93,.upon which shaft 93 the disc 81is loosely mounted and the toothed elem-ent'80 is secured. The shaft 93 is connected by means of intermeshing gears 94-95 preferably .of the beveled type, with-the .shaft 13. Thus it will be seen that motion will be imparted from the shaft 13 Achute 41 when the ejector 72 is advanced and the element 11 retracted. If desired, however, this platform 96 may be omitted as well as its support therefor so. that, if desired, when the ejector or plunger 11I is'y retracted articles may be allowed to pass out of the chute 41 and be superposed. upon the supporting platform while the already superposed articles upon the supporting platform- 10 areheilig ejected or ymoved therefrom into the case 7 3 by the plunger 72.

lVhen'the last supply of articles is delivered into the case 7 3, the case will be automatically stripped from the' tubular member 74 while the delivery of the supply of articles `by the ,plunger 72 which caused the case tobe removed from the tubular member 74 will remain within the tubular member 74 to be delivered into the next case which is placed in position upon the tubular member 74.

With this improved construction thearticles will be delivered by the conveyor 34 into the chute 41 and willbe dropped therefrom on to the supporting platform 10 in advance of the plunger or ejector Aftera predetermined number ofarticles have' thus been superposed the ejector o1; plunger 11 will be operated while the ejector or plunger 72 is retracted and in an inoperative position. Upon the movementV or retraction of the plunger 11 the plunger or ejector 72 willvbe rendered active while the plunger or ejector 11 is idle. Thus the plungerswill work in alternation with each other at predetermined times in the cycle of operation of the machine, the plungers or ejectors working in planes intersecting each other.

While the preferred formv of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope'of the claims,.without departing from the spirit of this invention.
